The EDS-305 Series from Moxa provides a compact and cost-effective solution for industrial Ethernet applications. These 5-port unmanaged switches feature a built-in relay output for power failure and port break alarms—an essential function for quick fault identification in mission-critical environments.

The switches include broadcast storm protection and are available in standard and extended temperature versions (-T), ensuring reliable performance from -40 to 75 °C. Their rugged metal housing with IP30 rating makes them suitable for deployment in hazardous areas, including ATEX Zone 2, IECEx, and Class I Div. 2 certified locations. Easy DIN-rail mounting allows for quick integration into control cabinets.
